This is an original fantasy TTRPG that you can play for free
This is a turn-based game, meaning when you go into battle, all of your characters go first, then all of your enemies go, and it continues until one side is killed. And when you explore a room, you go your speed, then the next moving thing goes their speed, and so on. No matter what, when a dice is rolled, the lowest number is the tamest, and the highest number is the most intense. You only need this story, a pencil and paper, and a six-sided die to play (if you have more dice, it somewhat increases the speed of rolling at times)
Feel free to make your own supplements and homebrew, as long as you give me credit for the original work
